Calling it an insult after making it assemble a special bench, the Supreme Court today ticked off the Sahara group and its chief Subrata Roy for not coming out with a proper proposal for refunding Rs 20,000 crore of investors money and asked it to come out with an "honourable" plan.

At this, the bench said that it can make arrangements to allow Subrata Roy's financial consultants and lawyers to meet him in custody but made it clear that there is no way of getting away from paying the amount.

"For the last one and half years he (Roy) has been out and he has been behind only
